Part of me is probably more conservative than people realise. I like my old string quartets, I don't like music that's trippy for trippy's sake.

In school, I guess I was a difficult, know-it-all type of student... I was always complaining that music education was too academic.

I thought I could organise freedom/How Scandinavian of me.

I feel the 21st century is another new age. Not only can we collaborate again with nature, but we have to. It's an emergency.

I've never done an album like this. With Biophilia, I was being like Kofi Annan - I had to be the pacifist to try to unite the impossible. Maybe that was a strange, personal job between me and myself, to show how overreaching I was being as a woman. The only way I could express that was by comparing it to the universe.

I'd done three solo albums in a row, and that's quite narcissistic.

I am grateful... grapefruit.
